What your result means
List it at is the price to put on the item so that your target lands in your balance. You actually receive is what you really get — sometimes a Robux or two above your target, because Roblox deals in whole Robux and the price has to round up to reach it. If that overshoot matters (say you are matching a round 1,000), nudge your target down by one and check again.
Why you cannot just add 30%
The instinct is to take your target and add 30%. That undershoots: 350 plus 30% is 455, and 455 minus its own 30% fee is only 318 — 32 Robux short.
The fee is charged on the list price, not on your share, so you have to divide rather than add. 350 ÷ 0.70 = 500, and 500 minus 30% is exactly 350. The bigger the fee, the wider the gap between adding and dividing.
How it works
Your share of a sale is the list price multiplied by (1 − fee). To invert that, divide your target by the same factor. The result is rounded up to a whole Robux, because a fractional price cannot be listed and rounding down would leave you short. That rounding is why the Robux you receive is occasionally a little above your target rather than exactly on it.
How to use this calculator
- Enter the number of Robux you want to end up with.
- Leave the fee at 30% unless you know your sale type differs.
- Use List it at as the price on your game pass, developer product or avatar item.
- Check You actually receive — if it overshoots your target and you need an exact figure, lower the target slightly.
- Pick a currency and paste an exchange rate to see the cash value of your share.
Formula
Target is the Robux you want to keep and Fee is the commission percentage. Dividing by (1 − fee) reverses the deduction; rounding up guarantees you are never left short. With the standard 30% fee the divisor is 0.70, so the list price is always your target divided by 0.7.
Example calculation
You want to clear 350 Robux from one sale, at the standard 30% fee:
Divisor: 1 − 0.30 = 0.70
List price = ceil(350 ÷ 0.70) = 500 R$
Roblox takes 150 R$
You receive 350 R$ — exactly on target
Targets rarely divide this cleanly. Ask for 100 Robux and the price is 143 (100 ÷ 0.7 = 142.86, rounded up), which nets you 100 Robux with 43 to Roblox.
Frequently asked questions
Why is the list price not just my target plus 30%?＋
Because the fee is a percentage of the list price, not of your share. Adding 30% to 350 gives 455, but 30% of 455 is 136.50, leaving you 318 — short of target. Dividing by 0.70 gives 500, which nets exactly 350.
Why do I sometimes receive slightly more than I asked for?＋
The list price is rounded up to a whole Robux so you are never left short, and that rounding can push your share a Robux or two past the target. Roblox does not credit fractional Robux either, so a small overshoot is the safe outcome.
Can I use this for group payouts?＋
Set the fee to 0. A group payout has no marketplace commission of its own — the fee was already taken on the original sale — so the list price and your share are the same number.

Assumptions & limitations
Every figure here comes from a simplified model. Keep these limits in mind when reading your result:
- The default 30% is the standard marketplace commission; Roblox can change it and some sale types differ.
- Prices and balances are whole Robux, so the list price rounds up and your share rounds down.
- Cash values use the standard DevEx rate of $0.0038 per Earned Robux and whatever exchange rate you enter — nothing is fetched live.
- Payment fees, the 30,000 Robux cash-out minimum and any tax are not applied here.
